Answer:

The answer is 16π inches

Step-by-step explanation:

Given;

  • The area of a circle is 64π in²

To Find;

  • The circumference of circle = ?

Formula;

  • Area (A) = πr²
  • Circumference (C) = 2πr

Now,

A = πr²

64π = πr²

Divide both side by π we get,

64π/π = πr²/π

64 = r²

r² = 64

√r² = √64

r = 8 Inches

Here, we got the value of r = 8 in.

Now,

C = 2πr

C = 2π (8)

C = 16π Inches

Thus, The circumference of circle is 16π Inches
